Splunk Core Certified Power User — Question 103

Which field will be used to populate the productINFO field if the productName and productId fields have values for a given event?

| eval productINFO=coalesce(productName, productId)

Answer options

• A. The value for the productName field because it appears first.
• B. Neither field value will be used and the productINFO field will be assigned a NULL value for the given event.
• C. The value for the productID field because it appears second.
• D. Both field values will be used and the productINFO field will become a multivalue field for the given event.

Correct answer: A

Explanation

The correct answer is A because the coalesce function returns the first non-null value, which in this case is productName since it appears first. Options B, C, and D are incorrect as they misunderstand how coalesce operates; it will not assign NULL, nor will it prioritize productId or create a multivalue field.
